Abstract (en)
[origin: US2014034858A1] A valve actuator for a rotary valve includes a piston and housing assembly, wherein axial movement of the piston along a bore of the housing causes an actuator rod to twist or rotate about an axis of the bore. The rotary motion of the actuator rod is caused in some arrangements by axial rotation of the piston along a helical housing wall and/or by axial rotation of a generally helical shape of the actuator rod engaged with a central opening through the piston.
